wt add subcommand

Maybe a wt add command would be nice. wt add feat-xyz would create branch if it does not exist and then use path ../feature-xyz. It should fail if ../feature-xyz directory already exists.

Hey @zbindenren thank you for the issue.

I have been thinking about adding more features to the script, but as the name suggests, the intention was to be lightweight and focus on switching between worktrees.

Not sure if it makes sense to add more subcommands.
Let me know your opinions.

It was just an idea. I understand when you want to keep it as is.
